Abstract: After briefly discussing the Internet of Things and Cyber physical device main features, their application in a specific architecture for a simple distributed intelligent system was presented. The systems work as a Multi agent system and it is based on Arduino Uno boards, each one hosting an intelligent agent. The system was developed as test equipment for an active intelligent water meter for a SMART CITY project. The proposed system can be generalized and usable also with very simple (and therefore economical) computational units and allows to delocalize in similar units the computational load exceeding the single node capability; a specific data protocol, based on I2C, is used to share the knowledge between agents
